Abstract

This work presents the thermophysical properties of carbon nanotubes (CNT) and CNT/Al2O3 hybrid nanofluids for heat transfer applications. An equal proportion of nanoparticles CNT (50%) and Al2O3 (50%) were added to the base fluid for two different concentration of 0.05 and 0.1%. Results show that addition of Al2O3 nanoparticles with CNT nanofluid improves the thermophysical properties. The thermal conductivity of hybrid nanofluids improved by 20% with a maximum concentration of 0.1%, while the thermal conductivity of CNT alone improved by only 8% with the base fluid. Similarly, density and viscosity of hybrid nanofluid increased up to 7 and 10%, respectively, while comparing it with the base fluid. The result of specific heat energy capacity of hybrid nanofluids increases to about 138% than CNT nanofluid with a maximum concentration of 0.2%. � The Institution of Engineering and Technology 2018.
